Taking the proven success of the Powercore 2, FMF created the Powercore 2 Shorty, with a shorter inner core length and aluminum canister. This design results in a finely tuned bolt-on performance silencer that maximizes bottom and mid-RPM power.

An excellent choice for tight tracks and supercross track applications.

The Powercore 2 Shorty silencer has a shortened inner core length and canister.

The shorter overall length allows for the exhaust gases to exit quicker giving the silencer better performance through the bottom to mid-range of the power band.

It is easy to perform maintenance on the Shorty silencer due to FMF using removable bolts which allow a simple break down.

Note: For closed course competition use ONLY. Not intended for street use.

Shorty for 300xcw

Coupled the Shorty with a Gnarly pipe to get some gains on the low end. It worked for what I was trying to achieve in allowing me to pull higher gears at lower rpm up hills to reduce wheel spin. The gains with this combo where not as massive as I was lead to believe in reviews. At least not on the 300 but these bikes already have huge torque. It was also quieter than the stock silencer

The silencer went on easy and sounds great. There may be a bit more power but it is hard to tell. The angle is kind of weird and the exhaust has blackened the inside of the plastic. The bike is definitely louder and sounds different from other bikes at the track. Like it don't love it.

I put this on my RM125. I honestly didn't think it would make the bike feel much different. But it made the 125 feel like a different bike. Before it had no low end power and a kind of jittery transfer when I hit the power band. Now, I can putt it around a lot easier in 1st gear and the power delivery is sooo much better when it hits the power band. I highly recommend this product and I can't find a single thing to complain about. It's worth so much more than the price!!!

Fit's great, looks awesome, sounds good, only issue I see is that they don't include the two rubber mounting grommets that attach to the rear frame, I don't think that's too much to ask for two pieces of rubber.
